I'm looking for help with my Porco Rosso cosplay. I don't need it immediately as I plan to utilize it at Acen next year.

I've got an idea of what to get but a couple things are eluding me. Such as the moustached nose and the general outfit. Is it a flight suit, or khaki pants and a khaki shirt? I've already found where I can buy an aviator cap, glasses and scarf. The boots I can also get easily, as I'm looking for a new pair anyways.
